AUGUSTUS STANLEY; CFNEW BRITAIN, CONNECTICUT.

Letters Patent No. 7 7,779, dated May 12, 1868.

IMPROVEMENT IIN saw-HORSES.

l Beit known that I, AUGIUSTUVS STANLEY, of New Britairnin the county ofHartford, State of Connecticut, have invented certain newandusefldmprovements in Saw-Horses; and I do hereby declare that thefollowing is a full andexact description thereof.

' The object of my invention is to facilitate the stowage andtransportation of' these important devices, and

to Vafford a cbeap, eicienia and durable structure, which-may be foldedinto a small compass, and readjusted Ainto a workingecoudition rapidly,and with ,littlev labor and expense.

I'wll first describe Vwhat I consider the best means of carrying ont myinvention, and will afterwards designate the pointlwhich I believe tolbe new therein. The accompanyingdrawlngs form a part of thisspeciioation, Figure lis a side view, i

Figure 2 is an end view, and Figure?) is a top view,with.thepartsadjustedfor use. Figured is aside view,I and' Figure 5 isan end viewof my saw-buck, with the parts adjusted for packingandtransportation.

`Similar letters of reference indicate like parts in all the figures.".lints are employed merely to aid iu distinguishing parts, and do notindicate' differences of material. The material of the whole may-bo hardwood. A' are parallel pieces, of ash or other'wood, sawn in rectangularsections. a a are connecting-braces,

which muy be introduced by screwing, or otherwise,`to hold the'partsparallel iirmly in a fixed relation to eachl i other.. Band C arecorresponding. pieces, of ash or'other material, notched across withrectangularnctchs, a's

indicated by b, and c. Thesenotches .b and e extend obliquely across theinner faces of the parts B 'and C, and are of a little greater widththan the parts A A above described. Their depth is suicient to let. theparts A A' into the material of the parts B and'C to a depth oi', say,about one-fourth of an inch. i

D is a well-made cylindrical brace or airis, of ash or other suitablematerial. It is provided with-a head, d,

which is sunlr into the part C, as represented. The shaft or body of'thebrace D turns loosely inthe parts .C1 land A A, and is threaded into thepart B, as represented. f I n other words, a strong aud regular screw isprei 4ducedby handor bymachiue'ry, vwhich it is .not necessary t odescribe, von' the end-'of the brace D, as indicated by d', and acorresponding female screw is formed into the part B. Machinery forproducing these parts'iin common use, and is well known to workersinwood. The work may be e'ected very cheaply and accurately, I

and with the consumption of very little time or'expense. v

vIn order to t my saw-horses for packing and transportation, I introducetho screw tl but a little distance into the part B, and this allows theparts B and-C to extend at a suicient distance apart to embrace theparts AfA, and their connecting-braces a a, in the same plane, asindicated in fig. 4. This allows thsstructure to-,be

packed in a very small space. When it is desired to put the saw-horse inaconditiou for. use, it is-necessary simply to'turn the parts B'and C,so that they shallassu'nxe the proper angle with thepartsA A, and to'grasp the brace D rmly by the middle, -by both hands, and turnitforcibly around, so as to drive the threaded part d further into thepart B. This draws the parts B and C gradually together until the part-AA is'receivred.y

in the recesses or rectangular notches b c, and the whole is screwedtightly together in that'position..l The sawhorse is now ready for use,and willperform its ordinary functions in thesame manner as anvordinarysaw-horse.

This condition is shown in'gure 3. i Y l It may again be put in thecondition indicated gfZ and restred again inthe condition for .use asoften as may be required.

It will be observed that `the locking et ,the parts A A in'the notches bc, in the .parts B and C, allows the parts to be fixed very firm andrigid, so that there is no wear-or inconvenience in the use of thes'awfhorse duo to its collapsable quality.

i Having now fully described my invention, what I claim as'new, anddesire to secure byLetters Patent, is as follows:

I claim the folding parts A A', B, C, notched or recessed across, andadapted to lock into each othor,.an d be rigidly coiiued at the properangle by the aid of the screwbrace D d d', or `itsequivalent,substantially as and for the purpose herein specified. Y v
